Polar molecules (nrog +/- tsub) yog nyiam dej molecules thiab yog hydrophilic. Tsis muaj polar molecules yog tiv taus ntawm dej thiab ua tsis yaj hauv dej; yog hydrophobic.
Ua li no, puas polar molecules nyiam tsis muaj polar?
Vim yog dej polar thiab yog vaj tsis muaj polar , lawv molecules tsis yog nyiam rau ib leeg. Cov molecules ntawm a polar cov kuab tshuaj zoo li dej nyiam rau lwm tus polar molecules , xws li cov suab thaj.
Ib tug kuj yuav nug, ua li cas cov polar molecules react nrog nonpolar molecules? Polar molecules txawv ntawm tsis muaj polar molecules los ntawm muaj qhov zoo thiab tsis zoo xaus thiab muaj zog intermolecular rog ntawm kev nyiam. A polar molecule xws li dej muaj qhov tsis zoo kawg thiab ob qhov zoo kawg. The them kawg ntawm ib molecule yog attracted rau qhov oppositely them kawg nyob rau hauv ib tug nyob sib ze molecule.
Tsis tas li ntawd, yog vim li cas cov polar thiab nonpolar molecules repel?
Thaum tej yam txawv ntawm txhua qhov kawg, peb hu rau lawv polar . Ib txhia molecules muaj qhov zoo thiab qhov tsis zoo kawg, thiab thaum lawv ua , peb hu lawv polar . Yog lawv tsis kam, peb hu lawv tsis polar . Tej yam uas yog polar tuaj yeem nyiam thiab repel ib leeg (cov nqi sib tw nyiam, sib xws repel ).
Dab tsi yog qhov tsim nyog rau lub molecule los ua polar?
Yuav kom muaj ib tug polar molecule , yuav tsum muaj qhov sib npaug ntawm qhov tsis zoo them electrons nyob rau hauv lub orbitals ntawm lub molecule . Cov dipoles yog unequally them los ntawm cov net electronegativity ntawm lub molecule los yog los ntawm cov duab molecule ua rau qhov tsis zoo dipole.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Puas yog lub zog tsim cov tshuaj tiv thaiv biochemical uas cov organic molecules pab ob qho tib si electron txais thiab pub dawb?
Txhais kev fermentation. Lub zog tsim cov tshuaj tiv thaiv biochemical uas cov organic molecules ua haujlwm ob qho tib si raws li tus neeg txais hluav taws xob thiab tus neeg pub khoom tshwm sim nyob rau hauv cov xwm txheej anaerobic
Puas yog dej tiv thaiv tsis muaj zog tiv thaiv?
Kev sib txhuam yog lub zog tshwm sim los ntawm ob yam khoom sib tsoo ua ke. Huab cua tsis kam thiab dej tsis kam yog hom kev sib txhuam. Lawv hu ua non- contact rog
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
